A Think and say（想一想，说一说）
Thirty years ago
These days
参考句型：
Thirty years ago, Miss Liu ... to her family. These days, she ... with ...
答案：Thirty years ago, Miss Liu wrote letters to her family. These days, she makes video calls with her family on the mobile phone.
解析：
【分析】首先观察图片：Thirty years ago（30年前）的图是明信片，对应“写信”，需用一般过去时；These days（如今）的图是手机视频通话，对应“打视频电话”，需用一般现在时。再结合参考句型的结构，补全符合时态和语义的句子即可。
【解析】根据图片信息，30年前刘小姐给家人写信，write的过去式是wrote，因此用“wrote letters”；如今她用手机和家人打视频电话，“make video calls”表示打视频电话，主语she是第三人称单数，动词用makes，补充完整后符合要求。
【答案】Thirty years ago, Miss Liu wrote letters to her family. These days, she makes video calls with her family on the mobile phone.
【知识点】一般过去时、一般现在时、动词短语
【点评】本题结合图片对比过去与现在的通讯方式，既考查识图能力，又要求学生运用正确时态完成句子，巩固了基础语法和常用表达。

【分析】
本题需结合短文语境及时态变化（过去与现在的对比）补全单词，解题思路：先通读全文，明确描述过去的动作用一般过去时，描述现在的动作用一般现在时，再结合固定搭配和课文内容确定每个空的单词。
【解析】
1. 句意为“我问家人他们生活中的变化”，“生活”用复数形式lives，故填lives；
2. 由“In the past”可知需用一般过去时，“写信”是固定搭配write letters，write的过去式为wrote，故填wrote；
3. 由“Now”可知需用一般现在时，主语he是第三人称单数，“网上聊天”是chat with，chat的第三人称单数为chats，故填chats；
4. 由“then”可知需用一般过去时，“花费时间”是固定搭配spend time，spend的过去式为spent，故填spent；
5. 描述客观事实用一般现在时，主语high-speed trains是复数，“行驶”用travel，故填travel；
6. 由“in the past”可知需用一般过去时，“工作”是work，过去式为worked，故填worked；
7. 由“Now”可知需用一般现在时，主语she是第三人称单数，“开会议”是固定搭配have meetings，have的第三人称单数为has，故填has；
8. 由“Twenty years ago”可知需用一般过去时，“付现金”是固定搭配pay in cash，pay的过去式为paid，故填paid；
【答案】
1. lives 2. wrote 3. chats 4. spent 5. travel 6. worked 7. has 8. paid
【知识点】
